COAL-MINING MACHINE.

SPECIFICATION forming part of Letters Patent No. 344,610, dated June 29,1886.

Application filed March 16, 1886.

To all whom it may concern:

Be it known that I, WILLIAM A. WRIGHT,

a citizen of the United States, residing at Gen treton, in the county ofBurlington, State of New Jersey, have invented a new and usefulImprovement in Goal or Stone Cutting Machines, which improvement isfully set forth in the following specification and accompanyingdrawings, in which- Y Figure l represents a sideelevation of astone-cutting machine embodying my invention. Fig. 2 represents a top orplan view thereof. Fig. 3 represents a front View thereot'. Figs. 4 and5 represent vertical sections ofportions, respectively, in lines x .fr yy, Fig. l.

Fig. 6 represents a horizontal section of a portion in line z z, Fig. l.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a saw which is so mounted that it may beadjusted in various directions, as will be hereinafter fully set forth.

Referring to the drawings, A represents a frame or stand, and Brepresents a cross-bar which is connected with upright portions of saidframe by dovetailed or other joints, whereby it may be raised andlowered.

Fitted to the bar B by a dovet-ailed or other joint is a head, C, which,by means of ascrew, I), is adapted to be moved horizontally to the rightor left. Located within said head, and connected therewith by means ofpivots F, is a block, G, within which is a sleeve, G', through whichpasses the driving-shaft H, power being communicated to the latter inany suitable manner. To said shaft is secured a bevelwheel, J, whichmeshes with a bevelwheel, K, the latter being mounted on the saw-arborL, whose. bearings are on a bracket, M, which 4o is connected with thesleeve G', the latter carrying at one end a disk, N,which bears againsta disk, I), formed on the end of the block G.

Q represents a screw which extends parallel with the shaft H, and ismounted in bearings 45, It It', one of which is connected with the blockG, and the other is swiveled on the sleeve G',

it being noticed that the disk N is connected with the sleeve G' by afeather, so that both rotary and sliding motions may be imparted 5o tosaid sleeve aud the saw set at differentangles. In the disk N is a rowof openings arranged Serial No. 195,407. (No model.)

in curvilinear order, and in the disk P is an opening which may registerwith either of the openings in the disk N. A key or pin, N', is insertedinto the proper opening of the disk N, and enters the opening in thedisk P, thus locking the disk N and holding the sleeve G', andconsequently retaining the saw'in its angular adjustment. One ot' thepivots F has secured to it a lever, S, and the adjacent por- 6o tion ofthe head G has a number of openings arranged in curvilinear order,whereby said head, and consequently the sleeve G', may be turned on thepivots F, by which provision the saw may be raised and lowered, theshaft H and connected parts assuming the angle imparted to the sleeve,said lever being held by the pin or bolt S.

Owing to the screw Q, the sleeve G' may be moved in opposite directions,so that the saw 7o may advance against the stone or rock to be sawed orcut and returned therefrom, it being evident that the saw may also beraised and lowered both by the cross-bar B and the block G, and furthermoved in lateral directions and set angularly relatively to the positionor requirements of the material to be cut by the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters So Patent, is-

l. In a stone or coal cutting machine, the frame A, in combination withvertically-ad` justable bar B, the laterally-adjustable head C, theblock G, and the sleeve G', provided 85 with a saw having its journalbearing in a bracket attached to said sleeve, all substantially asdescribed.

2. The frame A, in combination with verticallyadjustable bar B, the headC, and screw 9o D, the block G, pivotally secured within the head C, thesleeve G', passing through said block G, the bracket M, secured to saidsleeve G', and having suitably journaled therein a shaft carrying a saw,and means, substantially as described, for securing the angularadjustment of said block G, all substantially as and for the purpose setforth.

3. In a stone or coal cutting machine, the

head C, with a series of openings therein, in Ico combination with theblock G, pivotally secured withinr said head C, the sleeve G', passingthrough said block G, the bracket M,forrning suitable bearings for theshaft L, carrying a saw, the lever S, secured to one of the pivots ofsaid block G, and pin S', all substantiallyas and for-the purpose setforth.

4. In a stone or coal cutting machine, the head C,in combination withblock G, with disks l?, having openings therein, sleeve G', passingthrough said block and provided with disk N, having openings thereincoinciding with the openings in the head C,the pin N', and the bracketM, attached to said sleeve G' and carrying Van 'arbor having a sawthereon, all substantially as and for the purpose set forth. 5. In astone or coal cutting machine, the head C, in combination with the blockG Within the same, the sleeve G', passing through the block G andprovided with brackets M, having an arbor carrying asaW, and means,substantially as described, for longitudinally adjusting said sleeve G',all substantially as described.

6. In a stone or coal cutting machine, the head G, with block G Withinthe same, the sleeve G', passing through the said block G and connectedto the' bracket M, the arbor L, carrying a saw, the screw Q, havingbearing R, connected to the block G, and bearing R', swiveled on thesleeve G', all substantially as and for the purpose set forth.

7. In a stone or coal cutting machine, the frame A, in combination withthe head C, means, substantially as described, for vertically andlaterally adjusting the said head, a sleeve passing through a block insaid head and provided with a bracket forming a bearing for thesaw-arbor, and means, substantially as described, for longitudinallyadjust ing said sleeve, all substantially as and for the purpose setforth. p

8. In a stone or coal cutting machine, the head C, with a series ofopenings, in combination with the pivoted block G, having the disk P,with a series of openings in the same, the sleeve G', provided with thedisk N, slidingly mounted thereon. the bracket M, carrying the shaft L,having a saw thereon, the lever S, secured to one of the pivots of theblock G, and having the pin S', the pin N', adapted to bind together thedisks P and N, and means, substantially as described, for longitudinallyadjusting said sleeve G', all substantially as and for the purpose setforth.
